ABB Smart control cabinets for cable and overhead-line networks

The cable network includes a large amount of

secondary and compact secondary substations

(CSS), especially with ring main units (RMU), and

the overhead-line network a large amount of

pole-mounted switch disconnectors and

overhead-line reclosers, of which only a few are

remotely controllable.

ABB’s smart control cabinet portfolio includes

four ready-made solutions for cable networks

(GAI) and four for overhead-line networks (GAO),

one for each of the four levels of functionality and

automation. In addition to the standardized

offerings, the cabinets can be flexibly tailored to

meet customer-specific requirements.

The range of control cabinets for cable networks

comes in different sizes and materials and can be

flexibly mounted to suit a variety of installations,

whereas the cabinets for overhead-line networks

have been adapted to withstand demanding outdoor conditions.
